Question

Scientists have come to the conclusion_______ the temperature on Earth is getting higher and higher.

A．what

B．that

C．which

D．when

Answer 1

B

試題分析：考查從句，從句the temperature on Earth is getting higher and higher不缺少成份，what表示…東西，可以做主語、賓語、表語；which表示哪一個，可以做賓語和主語；when關(guān)系副詞，表示時間；that只起引導(dǎo)作用，不做成份，所以選B
點評：做從句題時，首先看從句是否缺少成份，如果缺少就在關(guān)系代詞里找引導(dǎo)詞；如果不缺少成份，就在關(guān)系副詞里選擇引導(dǎo)詞
